Before the amplifier is plugged in, be sure its rated voltage
corresponds to the voltage of the AC power source to be
used. Incorrect voltage could cause damage to the
amplifier when the AC power cord is plugged in. Do not
exceed rated voltage by more than 10%: operation below
90% of rated voltage will cause poor performance or may
shut the unit off.
Leakage/Resistance Check
Resistance. Measure the resistance from either side of the
line cord to chassis ground. If it is less than 500k ohms, the
unit is defective.
WARNING! DO NOT return the unit to the customer if it
fails one of these tests until the problem is located and
corrected.

PSW-D112/DPS-12 CONTROLS AND THEIR FUNCTION
1. Power LED - Will illuminate when the unit is turned on
with the main power switch. This light will be RED when
the unit is plugged in and not receiving a signal; when
the PSW-D112 receives a signal, the light will cycle to
GREEN. If no signal is received after 10 – 15 minutes
the light will cycle back to RED (standby) until a signal is
present again.
2. Main Power Switch - Main Power Switch to the
PSW-D112/DPS-12; turn ON to energize the subwoofer.
Under normal operation, Power Switch may be left ON to
utilize the Auto ON/OFF feature. For extended periods of
non-use, or vacations, it is recommended that the
subwoofer's Power Switch be turned OFF.

OPERATION
Crossover Adjustments
Phase
High-Pass Control
Phase Control
If you hooked up your subwoofer as shown in Speaker
Connection 4 on page 9. you also have the capability of
adjusting the high-pass frequency. The High-Pass control
determines the frequency at which the main speaker will
start reproducing sounds. If your main speakers can
comfortably reproduce some low-frequency sounds, also
set this control to a lower frequency setting, between 50Hz –
100Hz. This will concentrate the subwoofer’s efforts to the
ultradeep bass sounds, while your main speakers continue
to reproduce the mid-bass information. If you are using
smaller bookshelf speakers that do not extend to the lower
bass frequencies, set the high-pass crossover control to a
higher setting, between 125Hz – 180Hz. With this setting,
your main speakers will not have the burden of reproducing
any low-frequency sounds.
The Phase Control determines whether the subwoofer
speaker’s piston-like action moves in and out with the main
speakers, 0° , or opposite the main speakers, 180° . There is
no correct or incorrect setting. Proper phase adjustment
depends on several variables such as room size, subwoofer
placement and listener position. Adjust the phase switch to
maximize bass output at the listening position.
Remember, every system, room and listener is different.
There are no right or wrong settings; any setting you choose
will result in excellent performance. Should you decide to
fine-tune your system for optimum performance, be patient
and trust your ears. It will be worth the effort involved to fully
“tweak” your system.
If you hooked up your subwoofer as shown in Speaker
Connection 1 on page 8, the high-pass frequency is fixed at
150Hz.
If you hooked up your subwoofer as shown in Speaker
Connection 2 or 3 on page 8 and 9, no high-pass control
adjustment can be made from the subwoofer. Unless you
receiver/amplifier incorporates a high-pass crossover, your
main speakers will continue to get a full-range signal.
Final adjustment and blending of the low-pass and
high-pass controls may evolve over several listening
sessions. A good starting point would be to set both the lowand high-pass controls to the same frequency and adjust
from that point.
Low-Pass Control
The Low-Pass control determines the highest frequency at
which the subwoofer reproduces sounds. If your main
speakers can comfortably reproduce some low-frequency
sounds, set this control to a lower frequency setting,
between 50Hz – 100Hz. This will concentrate the
subwoofer’s efforts on the ultradeep bass sounds required
by today’s films and music. If you are using smaller
bookshelf speakers that do not extend to the lower bass
frequencies, set the low-pass crossover control to a higher
setting, between 120Hz – 180Hz.

See Figure 4.
This method of hookup can offer the highest
level of performance for your complete
loudspeaker system. The PSW-D112/
DPS-12 incorporates a variable high-pass
crossover in addition to a variable low-pass
crossover. When hooked up as shown
above, the subwoofer will limit the
low-frequency information that is returned to
your receiver/amplifier. Your receiver/
amplifier does not need to waste valuable
power reproducing the low frequencies. In
addition, since no low-frequency information
is being sent to your main loudspeakers, they
are able to reproduce mid and high
frequencies with greater clarity

To:
This is considered a Minor repair
All JBL Service Centers
Models: PSW-D110, PSW-D112, ARC SUB 8, ARC SUB 10
Subject: Check Solder Joints in Event of Failure
Some performance related complaints in the PSW-D110, PSW-D112, ARC SUB 8 or ARC SUB 10 powered
Subwoofers may be caused by cold solder connections between the 28 pins of the Power Amp Module and the
main circuit board. When troubleshooting, failure to check these joints can result in erroneous conclusions or
wasted time.
In the event you receive a PSW-D110, PSW-D112, ARC SUB 8 or ARC SUB 10 Subwoofer with the
complaints “Dead, or No Output, or Motorboating (Oscillation)”, perform the steps listed below first before
any further troubleshooting takes place:
1) Unplug all cables, lay the subwoofer on a padded surface.
2) Remove all Philips screws around the outer perimeter of the amplifier faceplate.
3) Remove amplifier assembly; you should be able to remove the amplifier far enough out of the cabinet to service it
without removing the woofer wires.
4) Locate the Power Amp Module; it is the large gray component with a metal case. On the solder side of the circuit
board are the 28 soldered connections to the Module.
5) Regardless of whether you can visibly see breaks in any of the connections or not, carefully re-solder all 28 pin
connections, adding 60/40 rosin core solder. Take care not “bridge” any connections on the board with solder.
6) Inspect the solder joints to the main filter capacitors C1 and C2 on the main PCB and re-solder if needed.
7) Replace the amplifier assembly back into the cabinet; replace the screws.
8) Test the unit by applying a signal from a music source, adjust the volume to a moderate level and confirm the
original problem has been corrected.
IMPORTANT SERVICE NOTES: When testing the PSW-D, or ARC Series amplifier, a load must always be
connected to the output terminals, whether the woofer, or a 4 to 8 ohm resistive load.
All AC powered test instruments (meters, oscilloscopes, etc.) must have a floating ground, i.e. be connected to
an isolation transformer.

To:
This is considered a Minor repair
All JBL Service Centers
Models: PSW-D112 rev0*, DPS-12, PSW-D115
Subject: Check Ribbon Cable Connection In Event Of Failure
Some performance related complaints in the PSW-D or DPS Series powered Subwoofers may be caused by
broken or cold solder connections in the ribbon cable connector between the premamp and main PCB.
When this condition occurs, it may also damage the Input Op-Amps U1/U2.
When troubleshooting, failure to check this connector and Input Op-Amps U1/U2 can result in erroneous
conclusions or wasted time.
In the event you receive a PSW-D112*, DPS-12, or PSW-D115 Subwoofer with any of the complaints
“Dead, or No Output, or Motorboating (Oscillation)”, perform the steps listed below before any further
troubleshooting takes place:
1) Unplug all cables, lay the subwoofer on a padded surface.
2) Remove all Philips screws around the outer perimeter of the amplifier faceplate.
3) Remove amplifier assembly; you should be able to remove the amplifier far enough out of the cabinet to service it
without removing other connecting wires.
4) Locate the ribbon cable connector between the premamp PCB and the main PCB. See illustration.
5) Desolder the connection on that cable where the cable attaches to the premamp PCB; to access, you may have to
carefully remove or scrape adhesive from this area.
6) Cut approximately ½” of ribbon from the cable end, then strip enough of the insulator on each of the six conductors
to allow re-connection. Take care not to damage the wire. Solder the cable end back onto the premamp PCB.
7) Test the unit by applying a signal from a music source, adjust the volume to a moderate level and confirm the
original problem has been corrected.
8) If not, troubleshoot Op-Amps U1 and U2 by standard methods; replace if defective:
Make sure plus/minus voltages are present on pins 4 and 11.
Make sure DC voltages are not present at output pins 1,7,8,14. (See schematic)
Apply a signal and confirm there is an output on pins 1,7,8,14. (See schematic)
9) Replace the amplifier assembly back into the cabinet; replace the screws.
IMPORTANT SERVICE NOTES: When testing the
PSW-D or DPS Series amplifier, a load must
always be connected to the output terminals,
whether the woofer, or a 4 to 8 ohm resistive load.
All AC powered test instruments (meters,
oscilloscopes, etc.) must have a floating ground,
i.e. be connected to an isolation transformer.

TIP# JBLTT2004-02
Subject: PSWD112/115 WIRING TO REMOTE VOLUME/CONTOUR/LED CONTROL PLATE
A total of 9 wires travel from two Molex connectors on amplifier PCB to 334344-001 Control plate.
That control panel is attached by two screws on the inside of the cabinet; the woofer must be removed. The
wire cluster is glued into the cabinet opening at the rear of the control panel. The hot melt glue has to be cut
out and pried out, then the wire cluster should be re-glued after the control panel is serviced, for air integrity.
1) Two Black sheathed cables, each containing wire colors:
Black or Blue
White
Red
2) Three separate wires:
Red
White
Gray
At the Control Plate:
Volume pot: Black or Blue, White, Red
Contour Switch: Black or Blue, White, Red
Power LED: Gray, Red
Contour LED: White, Black w/ 10k resistor
* Rev1 version of the PSW-D112 subwoofer is easily identified by the absence of Center channel Input and
Output connectors, and is missing the“Direct Out” RCA connector.

NOTE: THE FOLLOWING PROCEDURES MUST BE FOLLOWED
WHEN INSTALLING NEW S53AMI/S64AMI AMP MODULES:
FAILURE TO FOLLOW ONE OR MORE OF THESE STEPS MAY
RESULT IN THE INSTANT DESTRUCTION OF THE MODULE WHEN
POWERED UP.
v+
1) Align white indent marker on Amp Module with indent marker on main
O/P
PCB; alternately observe position of label on the top of the module;
incorrectly replacing the Module 180° in the PCB slot will result in its
destruction.
2) All AC powered test instruments (meters, oscilloscopes, etc.) must
V-
have a floating ground, i.e. be connected to an isolation transformer.
3) Align and position the Amp Module before soldering.
4) Attach the amp Module with the mounting screws before soldering or

5) Use only rosin-core or non-acid core solder; thoroughly de-flux the
surfaces after soldering.
If the new S53AMI/S64AMI Amp Module has larger mounting hole(s) in
the case, and the stock screws no longer will fit, and screws of the
proper type cannot be obtained locally order:
